Initial Inspection and Diagnostic Overview

WINDSHIELD WIPER AND WASHER DIAGNOSIS

The windshield wiper and washer are controlled by Simplified Wiring System (SWS). For trouble-shooting, refer to Local Interconnect Network (LIN), SWS Diagnosis.

NOTE: Even when the ETACS-ECU has failed, the windshield wiper can work at low speed as fail-safe mode. (Normally, the windshield wiper operates when the ignition switch is at the "ACC"position. But, if it enters the fail-safe mode, the wiper can operate only when the ignition switch is at the "ON" position.)
